Yet i think my cluster is not active correctly. I don't happen to see in Windows Clustering Failover Manager the Site B and DAG 2 network cards when setting up a DAG...

I am wishing to respect following documents for the dag setup i've found trough the forums :

If i understand well documentations, here are the modifications i'm going to make for a deployement :

Thanks for your reply...
The link is the one i followed to setup Dag Configuration tests...

Yet As doubted, i have no communication between my two sites IP as it is not routed correctly..
Asking the question though i think i already know the answer : Is there a way in given IP Classes to setup a Dag configuration with IPsec compatible IP's, without modifying ipsec configuration ? (ex : Site A DAG1 : DAG
(Replication) : 10.10.21.1 (255.255.0.0) - Site B DAG2 : DAG (Replication) : 192.168.45.1
(255.255.255.0) for which i have an IPsec tunnel configuration set between the sites : It's a test purpose tunnel)

pinging each network interfaces shows trafic passing in each DAG replication networks so they communicate correctly...

Next Step : Setup the Dag based on your documentation...

Through EMC (why but why did i not go trough EMS) i setup the DAG Group with following tests parameters
Name : ExchangeDag
Witness Server : ExchangeCas02
Folder : C:\DAGWitness\

I then add my two servers and went through an error :
Cluster service did not manage to bring up or take down service or cluster application "Cluster Group". Ressources are maybe in failed state (Translated from french, sorry if not exact).. In any case : Error 1205

I then tried to bring DAG back to empty state, by removing both servers, and there was a new error (not noted though).
I have in Event Manager : Cluster Node Dag1 has been removed...

Yet :
DagExchange declares it has only one active server node : DAG 1
On node 1 (Dag1), there is no more Cluster Service active. but DAG 1 server still appears in DAG management Group trough EMS/EMC.
On node2 (Dag2), Cluster service is still active, and node appears in Failover Clustering management for ExchangeDAG name, but not in EMS/EMC any more.

If i try to remove DAG1 node, though EMS or EMC on DAG1 or DAG2 i have following Error :
Can't connect to cluster Service on given computer, assure they have qorum or are configuration only
Shell Command attempted :
Remove-DatabaseAvailabilityGroupServer -MailboxServer "DAG1" -Identity ExchangeDAG

I don't seem able to remove anything on DAG2, even if it declares it's in a cluster that doesn't appear in exchange anymore..

Googling a lot on this crap, if you have any advice i'll take some...But i think i messed up something there ..

ActiveManager Operation Error : Cluster API 'OpenCluster (DAG1.domain)' failed with error 0x6d9 - There
are no more endpoints available from the endpoint

DAG 2 Cluster Service Cleanup : 9h05
Managed to remove Local DAG2 cluster node setup by destroying cluster in DAG2 Failover Clustering Management
Just need now to remove the exchange DAG setup and the lost node from EMC / EMS properties..

DAG CleanUP Done ! 9h30
For Personnal FollowUP : Remove DAG Server with configurationonly switch on lost cluster nodes, cleans up DAG membership.. Following removals done
Restarting My Configuration, and going a bit more slowly.. I think i found an AD latency issue that could have been responsable of faced problems... AD Team on the problem..

If i attempt to force it online i get following error message :
An error occured when attemtping to bring online following ressource : IPv4 Static Adress 1 (Cluster Group)
error Code : 0x80071397 : The cluster node is not the ressource owner or the node is not an owner possible of the ressource..

Does it tell you anything ? Is this normal ?

Thanks anyway by advance for all support given.. Really helped me get down to the right information...
I leave my edits for those searching documentation...
